Haha that's the truth. These trees will be going at my house which is around 2 acres open and surrounded by woods. Plus many big oak trees in the yard as well. Can definitely fit 3 in the one area, there is currently a tree up top that produces tons of small crabs that really draw in deer, plan to put a tree next to this one too. So 4 trees for the yard this year, can't wait.
By including a chestnut crab, you should have no pollination issues at all. If you can see these trees from the house, you'll probably come to know the different family groups and bucks that frequent your property.
